Months after selling its mobile business to Microsoft, Nokia has officially ended support for Symbian and MeeGo apps. The Finnish company has abandoned the two home-grown mobile operating systems in favor of Microsoft’s Windows Phone.

The Symbian Signed Team announced the end of support for Symbian and MeeGo apps via Twitter. The tweet said, “That was it; we are officially closed. Thank you all for the past years!”

the company said Thursday on its Symbian Signed Twitter account. Not long after announcing the sale of its devices and services business to Microsoft, Nokia told developers that as of January 1, 2014, they would no longer be able to offer up new apps or update existing apps in the Nokia Store for the two largely defunct mobile OSes.

Nokia had said that it had decided to focus its support and investment in new content towards Asha, the company’s feature phone platform, and Windows Phone.

With this move, Nokia has finally bid farewell to its old software platforms.
